Outline of Final Research Achievements

We investigated thermal characteristics about internal induction heating typed mixing system with water, 60wt% and 80wt% glycerol solution.The impeller is semi-sealed typed impeller which consists of coil and 2 sheets of mixing impeller plate. Induction heating coil is planar coil made of cupper, and mixing impeller plate is made of stainless steel of □150mm×3mmt with 4 rectangular holes. Heat transfer coefficient between this impeller and solution is calculated with equation W=hAΔT(W: heat rate, A: heat transfer area, ΔT: average temperature difference between impeller and solution). Next, h is and correlated by empirical formula and finally rearranged by the form of j factor.
j-factor of induction heating mixing impeller is 2.0 more times as much as that of vessel wall. The time variation of ΔT was well approximated by a primary delay system. Its time constant is 6~25s, its value is about 1/10 times as the conventional outer heating wall type and is proportional to 1/h.

Academic Significance and Societal Importance of the Research Achievements

撹拌槽は工業的バッチ生産の汎用装置であり、熱的制御は主に外部ジャケットからの熱媒体の加熱により行われている。ゆえに、熱容量が大で遅速な制御しか行えないため、現状では、応答性に優れた精密制御は行われていない。本提案の誘導加熱撹拌翼は内部加熱であり、過去、その翼伝熱特性について論じられたことはない。また、伝熱特性や熱応答に優れた誘導加熱型撹拌方式であるため従来のバッチ式では実現しえない高応答性と大容量化が可能となる。結果、dynamicに加熱制御しうるインテリジェントな撹拌反応システムを構築でき、高収率化と高品質化が実現すると考えられ、本成果は現行のバッチ式の革新につながる。
